DETAILED DESCRIPTION OF THE INVENTION

A portable handheld static-electricity generator for alleviating pain in patient's portion of body is hereby presented in a non-limiting manner. This electro-static field generating medical device is characterized by a movable brush and rubbing-surface upon which said brushed rubs such that static electricity is generated.

The term “silicone” broadly refers hereinafter, in a non-limiting manner, a sheeting, beads or pieces of rubber, plastic, glass, pith, and polymer in any form which is made from inert, non-reactive silicone, for example polydimethylsiloxane or related polysiloxane materials (represented generally by the structure R₂SiO, where R is a monovalent organic radical, including for example a methyl, ethyl, propyl or phenol group, among others and which may be several thousands of S—O units or more in length and that can build up static electricity on it.

According to one embodiment of the invention, this medical device is characterized by an automatically-operated mechanical unit and a silicone sheet assembly. The mechanical unit comprising a DC motor and gear-head thereof, provided in connection with a spur gear by means of a worm gear. A brush assembly, comprises a brushing member made of Kevlar, rubber, fabric, leather or any other suitable material and a brush body, is reversibly or irreversibly attached on the spur gear. The silicone sheet assembly comprises a silicone sheet and base thereof. This sheet is shape in a suitable manner: a planer sheet or 3D designed one (e.g., with a concaved or polygonal structure etc.), smooth or with textured surface etc. This silicone sheet is positioned adjacent to the brushing member, pressed against the silicone sheet inner surface by a spring such that by operating the motor, the spur gear circulates the brush, which is continuously rubbing the silicone sheet for a predefined time t, thereby generating static electricity upon the sheet, by attaching the electrically-loaded silicone sheet to a patient's portion of body, pain is alleviated. The attachment force of the brush to the silicone sheet, which determine the friction and the resultant electrostatic field, can be adjusted by selecting the preferred spring.

The mechanical device, together with the battery pack is placed within a specialized fabric structure, which attaches the mechanical unit and the battery pack to the patient's body.

An embodiment of the invention is hereby schematically illustrated in a non-limiting manner:

Reference is now made to FIGS. 1a to 1c , showing general, top and bottom views of a portable handheld static-electricity generator 100, respectively. Upper cover 10 encloses an electric drive moving a brush over silicon sheet an internal side of silicone sheet 50. In FIG. 1c , an external side of silicone sheet 50 is visually available. Numeral 40 refers to slots for straps securing generator 100 to the patient's body (not shown). LED is designed for indicating an operating mode of generator 100.

Reference is now made FIG. 2, presenting an internal prospective view of an upper cover of portable handheld static-electricity generator 100. Electric motor 25 secured by a clamp 23 energized by an electric battery (not shown). Rotation from electric motor 25 is transferred to screw 24 via shaft 27. Screw 24 is coupled with cogwheel 26.

Reference is now made to FIG. 3 presenting an internal prospective view of lower cover 30 of portable handheld static-electricity generator 100. Numeral 35 refers to a brush lifter. Operation principle will be explained below.

Reference is now made to FIG. 4 presenting lower cover 30 is formed by a two

rings

37 and 38 between which silicone sheet 50 is secured. Screws 39 mechanically interconnect two

rings

37 and 38.

Reference is now made to FIGS. 5a and 5b presenting exploded views of an electric drive at different aspects. As described above, electric motor 25 rotates screw 24 coupled with cogwheel 26. The aforesaid cogwheel 26 carries brush 31 which moves together with cogwheel 26. Specifically, brush 31 is pivoted on axis 37. Numeral 41 refers to a printed circuit board (PCB) functioning as a control card. PCB 41 is secured to upper cover 20 by means of screws 39 and nuts 45. Brush 31 is forced to silicone sheet 50 by spring 32 secured by a stopper 33.

Reference is now to FIGS. 7 and 8 illustrating operation of photo-microsensor 51 constituting an optoelectronic pair of a light source and a light detector (not shown). A member 53 carried by cogwheel 26 blocks a light beam from the light source to the light detector and electric motor 25 is stopped. End of session: According to an embodiment of the invention, the session lasts about t seconds; t is ranging, for example, from 4 to 8 seconds; whereas t can be modified by the patient or by his/her physician. By the end of the session, the brush needs to be detached from the silicone sheet. This is achieved by the following: after predefined duration or otherwise by means of an online-feedback manner lasting t seconds, the brush meets a brush lifter, which detach it from the silicone sheet. At the same time, a ‘fin’ from the spur gear get into the photo-microsensor which notify the software that the brush has been detached and the motor is stopped.

Daily operation of the portable handheld static-electricity generator as defined in the aforesaid embodiment in 8 sessions per day, 4 seconds each, alleviates joint pain and improves Wong-Backer Face Scale in one unit after one week. Graphs of RPM and electric field in each session are shown in FIG. 9.

Graphs of RPM and electric field in each session are shown in FIG. 10.

Example 3

Daily operation of the portable handheld static-electricity generator as defined and described in aforesaid embodiment in 6 sessions per day, 14 seconds each (each session comprises introduction of a pulsed electrostatic field, n=10), alleviates muscle pain and improves Wong-Backer Face Scale in one unit after one week of treatment. Graphs of RPM and electric field in each session are shown in FIG. 11.

Example 4

Daily operation of the portable handheld static-electricity generator as defined and described in aforesaid embodiment and further comprising electrical means for regulating electrostatic field (coil, capacitor etc) in 4 sessions per day, each treatment provides for 14 seconds (at least half of the sessions include introduction of a pulsed electrostatic field, n=9), alleviates joint pain and improves Wong-Backer Face Scale in one unit after one week of treatment. Graphs of RPM and electric field in each session are shown in FIG. 12.

Example 5

Example 6

Another object of the present invention is to provide means and methods of a non-invasive treatment for chronic pain relief by utilizing a semi conductive diaphragm of occlusive silicone sheeting of a thickness between about 2 and 4 mm thickness.

Hence according to an embodiment of the invention, an attached mechanism generates in either a continuous or pulse-wise manner a negative static electrical charge of about 10 to about 20 kilowatts per square inch that is applied to the silicone, providing large amount of negative ions that are being used for treatment.

The continuous charge of ions avoids electrical charge decay due to environmental and patient conditions such as humidity, temperature and perspiration. The negative ions on the silicone repel circulating negatively charged components on the painful area of the body surface over which the device is applied and attract positively charged components, as a result of which a beneficial effect on pain will be accrued.

A pain scale measures a patient's pain intensity or other features. Pain scales are based on self-report, observational (behavioral), or physiological data. Self-report is considered primary and should be obtained if possible (since pain is a quale by definition, and therefore assessment based on any set scale of expected outcomes from similar cases can fail to provide useful clinical data). Wong-Baker FACES pain rating scale, for example, shows a series of faces ranging from a happy face at 0, “No hurt” to a crying face at 10 “Hurts worst”.

A set of three different devices are useful for pain relief by reducing Wong-Baker FACES pain rating scale in at least one unit (n=23). In a first device, static electricity density of 15 KV per square inch is applied to a semi conductive material such as silicone sheeting as a barrier; in a second system, a static electricity density of 15 KV per square inch that is gradually released from a silicone sheeting to a Human's skin; and in a third system, a static electricity device that generates about 10 to about 20 KV per square inch according to a predefined protocol (see e.g., Example 5).
